You would eat less, drink less, travel less. Americans that get cleaned out could easily end up without anything to eat, or drink, or (hah) travel. According to feedamerica.org, 16.1% of Americans (as of 2011) already live in food-insecure households. 15% live in poverty. If you're impoverished and being helped by the state - i.e., Social Security - your aid checks are going to be direct-deposited into that swindled / frozen-while-we're-fixing-things account. When you're living on a pittance, you know how rough it is to not have that pittance for a month or three?

You're talking about eating less. You're talking about still being able to travel. I'm talking about a country where roughly one-sixth of its population would literally starve if this happened to them.
